good game, but:
stock tires on all cars are GARBAGE (crappiest wal-mart tires ever)
drivatar sucks. It uses a point based system, which sometimes makes absolutely no sense (sweepers and kinks specifically) and it doesn't actually mimic your driving style, it just uses the points to determine how well you take each kind of turn. Decent for lazy people, but I'd never personally use it

Have you ever driven a car at speed around a course with stock tyres on? If you have then you have a basis to make that sort of comment, I personally find stock tyres are poor quality and do tend to slide a lot (in real life), being a police response driver you tend to get taught how to drive fast using this setup. So before you make a comment, try driving a car at 100+mph around a corner and see how much it does slide.

ive been a GT fan all my life.. but i bought an xbox when i moved away, can this compare to the GT series? is it any good?

I've played all the GT games, bought a PS2 for GT3, then sold it, bought a slim PS2 for GT4... and then got an XBox for Forza

Forza is much, much better. Not as many cars, but there's actual racing unlike in Gran Turismo. IMO, it feels a lot like TOCA 2, which I really enjoyed. Oh, and it has all the Ferrari's and Porsche's GT didn't get.

yes, yes I have, many, many times. also if you're driving a high-end vehicle, it will have better tires on it, not the same crappy ones the ford focus for instance comes with.

Before making such a moronic comment and rolling your eyes, maybe you should wait for a response as to whether or not I have the right to make such a comment.

except for the supercars, whats wrong with stock tyres on everything else? thats the point of the upgrade system. either way, it's a great game. i bought a ps2 just for gt4, which is still a great game. the only thing i need is a good steering wheel.

The one thing I notice in all car racing sim games; all you have to do win is get enough money to make your car really fast and maybe improve tires/handling a little so you don't even have to be that good at taking the turns. Then you just beat everyone on the straights. Gets a little boring after awhile.

I find the AI to be better than GT4. In GT4, the cars followed their lines utterly perfectly, which is fine, BUT THEY WOULD NOT ALTER THEIR LINE. I once stopped on the course and waited for them to make a lap, and sure enough, the car came around and plowed right into me. In Forza, the cars will avoid you, and wont always take the "perfect" line, they will play aggressive, and even try to cut corners to get ahead of you. (Like the corkscrew in Leguna. One car tried to pass me by cutting the dirt.)
